..if it can even do that?
I’m setting up a temporary fence for a couple of horses and I’m so confused, I find energizers with 12volts and ones with 20.000 volts. I’ve borrowed one with 9500 volts, and 1,5 joule, that I’m hoping won’t fry my thread (0,35 ohm, one copper thread and 4 stainless steel ones).
In: Engineering
1.5J is not a lot of power at all. It is about the energy required to heat up 4g of copper by one degree C. And that is the energy that is contained in one pulse. The electric fence energizer outputs a high voltage but very low current and therefore there is very little energy in it. On top of that it only outputs a single pulse about once a second which further reduces its energy throughput. It is specifically designed to hurt you but not do any damage. They can use different circuits to get the high voltage that they need. They charge up capacitors which takes about a second and then discharges them over the outputs. And despite the high voltages involved there is very little energy in them.
